Severity of gastrointestinal bleeding is similar between patients receiving direct oral anticoagulants or vitamin K antagonists.

BACKGROUND: Gastrointestinal bleeding (GIB) is a common adverse event related to anticoagulation therapy. However, evidence comparing the severity, etiology and outcome of GIB in patients taking direct oral anticoagulants (DOAC) vs. vitamin K antagonists (VKA) is scarce. AIMS: To evaluate the severity, etiology and outcomes of GIB in patients under DOACs compared to VKA. METHODS: Patients under oral anticoagulant therapy admitted to the emergency department with acute GIB were prospectively recruited from July 2016 to January 2018 at a tertiary referral hospital. Demographic and clinical outcome were obtained from medical records. Severity of the GIB event was classified as mild, major or severe according to clinical presentation and the type of support needed. Etiology and location of bleeding, number of packed red blood cells transfused (PRBC) and length of hospital stay were recorded until discharge or in-hospital death. RESULTS: A total of 208 patients with acute GIB under oral anticoagulant treatment were recruited: 119 patients were on VKA and 89 patients on DOAC with similar characteristics. Thirty-one patients had severe GIB; 134 major and 43 mild, with no differences in severity, number of PRBC and length of hospital stay between the groups. Peptic disease was the most frequent etiology of GIB in patients on VKA (20.2 % vs. 13.6%, p=0.20). Diverticular bleeding was the most frequent adverse event in patients on DOAC (14.3% vs. 24.8%, p= 0.056). CONCLUSIONS: Severity and clinical outcomes of GIB are similar between patients on DOAC and patients on VKA, regardless of etiology of GIB.

Opioid-induced esophageal dysfunction - Prevalence and manometric findings.

BACKGROUND: prescription opioid use is on the rise. There has been an increasing recognition that chronic opioid consumption can result in esophageal motility disorders, and this association has been named opioid-induced esophageal dysfunction (OIED). AIMS: to analyze the prevalence of chronic opioid consumption in patients referred for esophageal motility testing in a European center; to describe the clinical characteristics and the association of opioid consumption with esophageal motility disorders. METHODS: a retrospective, descriptive study in patients who had undergone an HRM in a single center. The clinical history in the electronic medical records was reviewed. RESULTS: the prevalence of opioid prescription in patients referred to our institution was 10.1 %, and 4.8 % of them were chronic active opioid users. There was a 32 % prevalence of OIED. Comparing chronic active opioid users (CAOU) with OIED and CAOU patients without OIED, there was a higher prevalence of males (43.8 % vs 8.8 %; p-value = 0.007). Converting the different opioid medications to morphine milligram equivalent daily dose (MMED), CAOU patients with OIED had a higher MMED than CAOU patients without OIED (125.2 ± 31.3 vs 33.4 ± 5.7 MME; p = 0.041). Dysphagia was the most common indication for performing an HRM in 60.0 % of CAOU patients. Furthermore, dysphagia was more frequent in CAOU patients with OIED (87.5 % vs 47.0 %; p = 0.019). CONCLUSIONS: chronic opioid users with OIED complained mostly of dysphagia. There was an association of male sex and a higher dose of opioids in CAOU patients with esophageal motility disorders.

Endoscopic stenting for gastroduodenal outlet obstruction of a malignant origin, real life experience in a single center.

AIM: to evaluate the safety and effectiveness of self-expandable metal stent placement for malignant gastric outlet obstruction (GOO). METHODS: a retrospective, analytic cohort study at a single, tertiary-care center. RESULTS: thirty-six patients that underwent stent placement for GOO of malignant origin were identified during the study period. Technical success was achieved in 36 (100 %) patients and clinical success was achieved in 31 patients (86.1 %). Before the procedure, 17 (54.8 %) patients had a gastric outlet obstruction score (GOOSS) of 0, which is a complete inability of oral intake. Twenty-three patients were alive 30 days after the procedure, two (8.6 %) patients had a GOOSS of 1, ten (43.3 %) had a GOOSS of 2 and eleven (47.9 %) had a GOOSS of 3. Abdominal pain was present in all 31 patients before the procedure and only seven (22.6 %) patients continued with abdominal pain 24 hours after the procedure. During follow-up, ten (30.3 %) patients developed complications related to the stents and none of them was fatal. Additional therapy due to partial occlusion of the stent was necessary in three patients. The stents functional duration had a median of 72 days (IQR 25-75 15-105 days) and was closely related to overall survival. CONCLUSION: palliative stenting for gastroduodenal obstruction is a safe, feasible and effective therapy to treat patients with malignant gastric outlet obstruction.
